JXR to CG4 Conversion: FAQ

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression. Its 48-bit RGB color range allows for accuracy in rendering images and better graphic representation. Additionally, JXRs can include an alpha channel which facilitates the editing of transparent layers.
